Caratacus

Caratacus (21-50 AD) was King of the Britons from 43 to 50 AD, succeeding Guiderius and preceding Cogidubnus. He led Britonnic resistance to the Roman invasion under Emperor Claudius, but he was captured, brought to Rome, and strangled after the triumphal parade.

Biography
Caratacus was the son of the Catuvellauni king Cunobelinus and the brother of Guiderius, and he led the conquest of the Atrebates in 35 AD. In 43 AD, the Roman emperor Claudius used the Atrebates' conquest as an excuse to invade Britannia, and Guiderius was killed early in the Roman invasion. Caratacus used Camulodunon (Colchester) as his main base during his war against the Romans, and he lost much of the south-east after his defeat at the Battle of the Medway in 43 AD. In 50 AD, he was defeated and captured by Publius Ostorius Scapula, and he was brought to Rome as a captive. He was paraded as a part of the Roman triumphal celebrations and was then strangled.
